Murphy helps Mets walk off on Giants

First baseman rips game-winning single in bottom of ninth

NEW YORK -- On the heels of Saturday's 10-inning loss that also cost them David Wright, the Mets desperately needed a reason to smile.

So when Daniel Murphy delivered an RBI single in the bottom of the ninth inning, scoring Jeff Francoeur and giving the Mets a walk-off 4-3 win over the Giants, the home dugout finally had reason to celebrate, even if only for a few minutes.

"It's good to come in here and smile after a win," said Francoeur, who led the Mets onto the field in lieu of Wright. "And then of course you come in and you get the news about David [going to the 15-day disabled list]."

Such is life for the Mets (55-62), who battled their way back on Sunday afternoon but are buried in a pile of injuries that includes everyday starters Carlos Delgado, Carlos Beltran, Jose Reyes and now Wright.

"You just got to keep going on," said Francoeur, when asked about dealing with the team's catastrophic losses.

Added Murphy, who prayed for Wright in a chapel earlier on Sunday: "I just hope the Lord touches him and helps him with a speedy recovery. He was definitely in our hearts [Sunday afternoon]."

The Mets' win was certainly something Wright would be proud of.

Francoeur got the bottom of the ninth inning going with an infield single to Giants shortstop Juan Uribe's backhand side and reached second on a sacrifice bunt from Fernando Tatis. The Giants promptly yanked reliever Sergio Romo (3-2) in favor of Jeremy Affeldt, who hung a breaking ball to Murphy.

But the scales appeared tipped in the Mets' favor much earlier than that, as starter Mike Pelfrey bounced back from two subpar starts to give his club a top-notch outing.

The big right-hander didn't give up a hit until Fred Lewis doubled with two outs in the fourth inning, and Pelfrey economically and effectively discarded the Giants' lineup by using a heavy dose of his mid-90s sinker.

"He was outstanding today," manager Jerry Manuel said. "[He] was able to get those secondary pitches over for strikes, ran some balls in on some lefties -- that was very impressive."

The Giants (63-54) were in equal awe, with second baseman Freddy Sanchez giving Pelfrey kudos while talking to Francoeur.

"He was like 'Dang, he's throwing hard today,'" Francoeur said of the exchange with Sanchez. "[Pelfrey's] got a heavy, heavy ball.

"When he's sitting the sinker way in, you can't sit on a certain pitch when he throws 94-95 [mph] like he is. It's pretty impossible to hit."

Pelfrey was touched for one run on two hits in the fifth inning, and he didn't run into serious trouble until the eighth. He allowed a one-out double to Eugenio Velez, and Randy Winn doubled in the tying run, knocking Pelfrey from the game in favor of Brian Stokes. Stokes combined with Pedro Feliciano to record the inning's final two outs.

The Mets' first two runs came courtesy of second baseman Luis Castillo, who couldn't have picked a better time for his first home run of the season. Castillo's two-run two-out blast in the fifth frame served as the perfect pickup, sailing into the second deck of the left-field stands and energizing the crowd of 38,793 at Citi Field. Castillo's homer, which scored Angel Pagan, broke a drought of 333 at-bats this season without a dinger.
